The Cambridge University mathematician laid the foundation for the invention of software. As part of its anniversary celebration, BusinessWeek is presenting a series of weekly profiles for the greatest innovators of the past 75 years. Some made their mark in science or technology; others in management, finance, marketing, or government. In late September, 2004, BusinessWeek will publish a special commemorative issue on Innovation. Elsewhere, there is also a special article for Turing.

From Rodrigos Limk:
"In 1936 he published On Computable Numbers, with an application to the Entscheidungsproblem. It is in this paper that Turing introduced an abstract machine, now called a "Turing machine", which moved from one state to another using a precise finite set of rules (given by a finite table) and depending on a single symbol it read from a tape."

So he published his theory in the same year as Zuse started to build his Z1 (planing must have started at least one year before).
Again my question: What's so great about Turing?

@Aidan Mark:
Its about "The Cambridge University mathematician laid the foundation for the invention of software"
Just can't see what he did for the invention of software...
